Intermediate relay is a relay, which is composed of fixed iron core, moving iron core, spring, moving contact, static contact, coil, terminal and shell. When the coil is electrified, the moving iron core acts to pull in under the action of electromagnetic force, and the moving contact acts to separate the normally closed contact and close the normally open contact; When the coil is powered off, the moving iron core drives the moving contact to reset under the action of the spring.

在工業控制線路和現在的家用電器控制線路中，常常會有中間繼電器存在，對于不同的控制線路，中間繼電器的作用有所不同，其在線路中的作用常見的有以下幾種。

In the industrial control circuit and the current home appliances control circuit, there are often intermediate relays. For different control circuits, the role of intermediate relays is different. The common roles of intermediate relays in the circuit are as follows.

1、作用之一--代替小型接觸器

1. One of the functions -- to replace the small contactor

中間繼電器的觸點具有一定的帶負荷能力，當負載容量比較小時，可以用來替代小型接觸器使用，比如電動卷閘門和一些小家電的控制。這樣不僅可以起到控制的目的，而且可以節省空間，使電器的控制部分做得比較精致。

The contact of the intermediate relay has a certain load capacity. When the load capacity is relatively small, it can be used to replace small contactors, such as the control of electric rolling gate and some small household appliances. This not only can play the purpose of control, but also can save space, so that the control part of electrical appliances do more delicate.

2、作用之二--增加接點數量

2. The second function is to increase the number of contacts

在電路控制系統中，線路中增加一個中間繼電器，不僅不會改變控制形式、增加接點數量，而且便于維修。

In the circuit control system, adding an intermediate relay in the circuit not only does not change the control form and increase the number of contacts, but also is convenient for maintenance.

3、作用之三--增加接點容量

3. The third function is to increase the contact capacity

中間繼電器的接點容量雖然不是很大，但也具有一定的帶負載能力，同時其驅動所需要的電流又很小，因此可以用中間繼電器來擴大接點容量。而在控制線路中使用中間繼電器，通過中間繼電器來控制其他負載，達到擴大控制容量的目的。

Although the contact capacity of the intermediate relay is not very large, it also has a certain load capacity. At the same time, the current required for its drive is very small, so the intermediate relay can be used to expand the contact capacity. The intermediate relay is used in the control circuit to control other loads, so as to expand the control capacity.
